FBI snares $850 million Butterfly botnet ring with help of Facebook

On Tuesday, the FBI announced that it had arrested ten people connected to a botnet that had spread through Facebook. Spread by a virus targeting Facebook users, the botnet caused over $850 million in losses to financial institutions, infected over 11 million computers, and stole credit card and bank account data. The botnet itself was shut down in October, according to an FBI statement. This is the second major outbreak of botnets based on the Butterfly (aka Mariposa) bot tool. The first incarnation, discovered in December 2008 and shut down a year later, infected over 12 million PCs worldwide and was spread primarily through file-sharing and instant messaging attacks. It also harvested financial information from over 800,000 victims. In the latest incarnation of Butterfly, the botnet spread itself using variants of Yahos, a virus that spreads itself by sending links via social networks and instant messaging.
